Inert
Diamagnetic
Ferromagnetic

Observe the given figure. If the diode is an ideal diode, then what are the values of Io and Vo respectively?

0.2 A, 0V
10A, 2 V
2 A, 10 V
0 A, 0.2 V

ANSWER EXPLANATION DOWNLOAD EXAMIANS APP

Io = V/R = 20/100
Io = 0.2 A
Since the given diode is an ideal diode therefore there is no voltage drop across it.
Vo = Io × RD
Vo = 0.2 × 0
Vo = 0
Hence Io = 0.2 A & Vo = 0
